Borderline Personality Disorderand the serial bully

Some visitors to Bully OnLine have suggested that
the bullies in their lives exhibit characteristics of Borderline Personality Disorder.

It seems to me that in some cases Borderline Personality Disorder could be
the manifestation in adulthood of a psychiatric injury caused by childhood abuse
which may have been intentional or unintentional. In people whose behaviour
profile is inclined towards that of a target
the disorder seems to manifest in varying degrees as a sense of heightened
fragility. In people whose behaviour profile is inclined towards that of a bully
the disorder seems to manifest as aggression towards others as described on this
web site.

The main symptoms of Borderline Personality Disorder are:

Frantic efforts to avoid real or imagined abandonment.

A pattern of unstable and intense interpersonal relationships characterized by
alternating between extremes of idealization and devaluation (called
"splitting").
